The Combined Community Codec Pack(CCCP) is a simple playback pack for Windows with the goal of supporting the majority of video formats in use today. NOTE! If you install all the included codecs/decoders you might get problem with other video software on your computer.
Full description.

Somewhat overtime, but a new release - code name "Manatsu" (Midsummer) - has been released. As always, it contains fixes and optimizations found and done during the last release cycle.

! Known Issue !
Due to file parsing optimization done in xy-VSFilter, reading of external subtitle files that are not saved as unicode is borked by default in CCCP, and non-ASCII symbols will get broken in this case. As a workaround, if you tend to play such files, it is recommended that you enable the internal subtitle renderer in MPC-HC (View&#8594;Options&#8594;Playback&#8594;Use the built-in subtitle renderer)

This bug was never noticed by any of the CCCP crew, or the testers, until very late in the release cycle, and thus it was chosen that the release would be done with this known issue instead of either waiting more, or suddenly switching binaries around.

The plan is to have a new release soon'ish after this, and until then the workaround should be enough.

Updated components:
LAV Filters 0.62.0.0-a731178
MPC-HC 1.7.6 (master@ebc29cf)
xy-VSFilter 3.0.0."305" (git 7f6a318)
General change log:
MPC-HC
MPC-HC no longer crashes during quick seeks with PGS subpictures when the internal subtitle renderer was used. Did not affect CCCP defaults.
Anamorphic ASS is now handled correctly in the internal subtitle renderer. This is one of the oldest standing bugs there were regarding the ISR, and we all thank kasper93 for the effort he put into fixing this after Daemon404 successfully trolled people regarding it.
The Play&#8594;Filters filter listing can now be easily copied to the clipboard, there is now a button for that in the top of the listing.
UI language selection has been moved to the options in MPC-HC.
Minor fixes and improvements in general.
LAV
PGS subpicture parsing improved in LAV Splitter.
LAV Video now supports VP7 video (for the two of you out there with samples).
LAV Video can now use the Media Foundation WMV9 decoder instead of the old DMO decoder.
FFmpeg used in LAV now uses native win32 threads instead of a pthreads wrapper.
Various fixes included in the updated FFmpeg.
xy-VSFilter
VirtualDub library has been updated.
Various ASS parsing improvements by Plorkyeran. These also remove the A (ANSI/non-unicode code page) Windows API usage, which also breaks non-unicode subtitle parsing. As noted, MPC-HC's internal subtitle renderer should be used instead in case you play such files.
Loading of UUEncoded fonts from ASS files is fixed.
A possible out-of-bounds array access was fixed. This has been in the code for more than a year, and no-one noticed it. It seems that no-one has subtitle files with UTF-8 data that end up in this area of glyphs (or the rest of the code actually makes the bug impossible to happen).
Vobsub fixes that replace the old MPC-BE hackfix. Should lead to similar results as with the old hackfix, unfortunately. In MPC-HC these changes actually add proper fadein/-out.

New CCCP Win Vista - Win 7 - Win 8.x Release! (2014-04-20)

A new release, code name "A Dream of Spring", has been released. It contains various fixes to bugs found during the last release cycle. XP support is now officially off the table, but nothing has (yet) been broken knowingly for it.

Updated components:
LAV Filters 0.61.2.0-b02e0c4
MPC-HC 1.7.4.2 (master@f2fa14b)
xy-VSFilter 3.0.0."288" (git 974aff3)
General change log:
Installer and settings applications
The uninstaller should now no longer leave an empty root directory in case of a full uninstall under specific circuimstances.
MPC-HC
MPC-HC no longer moves a couple of frames forward when paused for the first time.
XySubFilter's auto-loading has now been fixed in certain cases on Windows 7.
LAV
The defaults are now much less restrictive format-wise for both the splitter and the video decoder. This should not bring up issues, but we welcome any reports in case of failure.
In LAV Video, VC1, MPEG-1, WMV3, WMV12 and MS Video 1 are disabled in addition to LAV Video's own defaults of disabling RV12, Cinepak, QPEG and MSRLE. The ones we disable are handled so as they are handled generally better by the official MS decoders.
In LAV Splitter, asf (WMV), avi, mp3, mpeg (MPEG-PS), wav and wtv are disabled, as these are known to be either handled well by the MS filters, or known to be problematic with some applications if replaced by non-MS filters.
LAV Filters' support for loading Avisynth scripts with itself being called within them has been improved. This fixes the last remaining problem left with using LAV for Avisynth scripts.
LAV Splitter is now more resilient to unexpected things in embedded cue sheets (in MP3 files, for example).
MP4/MKV files with H.264 and no parameter sets off-band (avcC) are now supported in LAV Filters.
Conversion of odd-height 4:2:2 and 4:4:4 YCbCr to RGB now works correctly in LAV Video. Fixes the bottom line in certain mirkosp's encodes, for example.
Crashes on SSE-only systems with DTS audio have been fixed.
DXVA2 decoder implementation has been improved in LAV Video.
xy-VSFilter
VirtualDub library has been updated.
Auto-loading of external subtitle files should now work with uppercase extensions.
A bug fix to allow larger borders in ASS rendering has been merged.

New CCCP Win XP - Win Vista - Win 7 - Win 8.x Release! (2014-03-09)

A new release, code name "Absurdum Ipsum", has been released. It contains a wide array of general improvements as well as fixes. Unless something surprising happens, this will also be the last release to get some kind of support on XP as its EOL date crawls closer.
Updated components:
LAV Filters 0.61.1.0-9cdf201
MPC-HC 1.7.3.91
xy-VSFilter 3.0.0."284"
General change log:
More detailed change log will be written after JEEB gets some sleep

New CCCP Win XP - Win Vista - Win 7 - Win 8.x Release! (2014-01-17)

What happens when we finally get enough fixes aboard? We release! Accordingly, a new release, code name "Ashinoko", has been released.

Updated components:
LAV Filters 0.60.1.0-22da8ba
MPC-HC 1.7.1.322 (shows up as 333)
General change log:
Installer and settings applications
WinCPUId is no longer used for SSE detection.
Default source filter for OGM is now set to LAV Splitter. A half-year old FFmpeg bug has finally been squished regarding seeking in this container, enabling this change to go forward.
MPC-HC
MPC-HC's VSFilter/ISR code has been reworked, and the ISR is now quite a bit faster with complex styled subtitles.
MPC-HC now has XySubFilter support in its EVR and VMR9-based custom renderers. After XySubFilter has been registered in the system, blocking the "DirectVobSub (auto-loading version)" filter in external filters is the easiest way to get it used with the standard CCCP setup.
The mouse cursor will now hide in windowed mode as well in MPC-HC when it is not moved for a certain amount of time on top of the video surface.
The menu bar can now be shown when hidden in MPC-HC by pressing the Alt key.
The shaders feature has been reworked in MPC-HC. Now the feature has a full page in the Options.
MPC-HC is now built with Visual Studio 2013.
LAV
WMA2 audio in Matroska no longer gets wacky timestamps with LAV Splitter, effectively fixing some older files with this type of audio muxed in.
Native MPEG-4 Part 2 (xvid, divx, lavc mpeg4) timestamps in Matroska are now handled correctly in LAV Splitter. Fixes stutter due to incorrect usage of the container timestamps with such files.
VC-1 decoding via DXVA2 has been fixed and re-enabled on Intel hardware in LAV Video. Requires relatively new hardware and drivers (Ivy Bridge/Haswell).
Various minor Matroska parsing fixes in LAV Splitter. Among other things, seems to fix playback of certain files with humongous FLAC extradata.
FFmpeg issue 2739 has finally been fixed. This fixes seeking in OGM files in LAV Splitter.
Forced subpicture and PGS subtitle stream selection has been improved in LAV Splitter.
Opus audio pre-skip support has been improved in LAV Audio.
FFmpeg's AAC decoder now supports correctly a few more types of AAC audio in LAV Audio.
Support for reading embedded Cue Sheets from audio files as chapters has been added to LAV Splitter.
Support for reporting the stream bitrate through IBitrateInfo (for MPC-HC et al.) has been added to LAV Splitter.
Additional metadata from the source file is now exported through IPropertyBag in LAV Splitter.
LAV Filters are now built with Visual Studio 2013 and GCC 4.8.2.

New CCCP Win8(.1)/Win7/Vista/XP Release! (2013-11-27)

After finding a small bugbear with the last release, it was decided to make a relatively small iterative update for it. Thus a new release came to be, which should fix a problem only a few users should have noticed, code name "Reticulating Splines With Movax"!

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
LAV Filters 0.59.1.0-6cdab1c
General change log:
LAV
DXVA2ExtendedFormat colorimetry is now disabled in LAV Video if the Overlay mixer is in the graph, except when LAV Video is connected to a VSFilter. This fixes a black screen problem that some XP users possibly encountered.
VC-1 and WMV decoding via DXVA2 is now specifically disabled with Intel GPUs in LAV Video. Latest Intel drivers contain the component which is used for this, but its usage leads to either a broken image or plain crashes.

New CCCP Win8(.1)/Win7/Vista/XP Release! (2013-11-24)

The time has come to let out some more things that have been under testing, including something we have been testing in DirectShow since early October - HEVC demuxing and decoding. A new release with some fixes and some new features, code name "Rusty Crap"!

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
Haali Package 1.13.356.20 (CCCP Build)
LAV Filters 0.59.1.0-fd21671
MPC-HC 1.7.1.24 (shows up as 39)
General change log:
Installer and settings applications
OGM and "normal OGG" (OGG, OGV) have been separated from each other in the system settings app, and only OGM is now enabled with the Haali's splitter. This enables us to specifically target the one type of format that doesn't work with libavformat, minimizing the unneeded usage of Haali's splitter.
The installer and uninstaller no longer touch a long-unused HKLM MPC ExePath key.
Everything has been updated to the new MPC-HC registry key
The user level settings application now disables MPC-HC's settings migration from the old key in case of a settings reset. Migration does not remove the original key's contents and thus leaving it it to activate would lead to extra funkyness during each and every settings reset.
The installer no longer tries to touch the default value from the MPC-HC key.
MPC-HC
MPC-HC has switched the registry key it uses. This can break various old software that depended on the old location, including GTSdll. The recommended solution is to switch to something that can use the web interface instead.
A problem with MPC-HC incorrectly pushing things onto the clipboard with the button in the about window has been fixed. Data on the clipboard will now not get destroyed if you haven't pasted it before closing the app.
MPC-HC now handles files with a single random access point as files that have no known random access points. This makes the player fall back from the fast seeking mode, and lets the user seek in such files.
Random access point information is now reloaded when a splitter calls a length change. This should fix seeking problems when switching between editions, for example.
MPC-HC should now report a human-readable error in case it fails to hook certain system functionality (usually due to certain kind of security software).
Various fixes and tweaks.
MPC-HC is now built with Visual Studio 2012, Update 4.
LAV
HEVC decoding support is added. Colorimetry information is also parsed from the stream and passed along.
HEVC demuxing support is added for the following containers:
Matroska and MP4, as both of these use a way of doing it based upon 14496-15, 3rd Edition.
MPEG-TS
VP9 decoding support is added.
A problem with the LAV Video and Audio tray icons crashing when you click them to open the property windows has been fixed. U78's patch forgot to initialize some values so a random memory location would be executed (and not executable regions would just go boom and crash).
LAV Video now handles Annex B H.264 in MP4. Such files are technically broken, but since various things can still handle them, it is good to have them work with LAV as well. This fixes the last remaining regression with decoding we had compared to the releases based on FFDShow-tryouts.
LAV Video now tries to detect from the pin info if the renderer "understands" (or "can handle") the DXVA2ExtendedFormat colorimetry information. This is less safe than the white list approach done with the last release, but it seems to generally work.
LAV Audio should now handle bit streaming changes while paused better.
DTS parsing in LAV has been improved, certain cases of data being read incorrectly as DTS-HD markers should now be fixed.
LAV Video should now not try to decode in case the internal decoder context is missing.
LAV Filters are now built with Visual Studio 2012, Update 4.
Haali Package
A change that broke Haali's renderer under certain circumstances has been reverted. This was an additional change on top of the top-down RGB preference, and thus does not affect the slowness fix for LAV Video + Haali's renderer with RGB output.

New CCCP Win8/Win7/Vista/XP Release! (2013-10-17)

We're moving to the darker time of the year again over at the northern hemisphere, but that doesn't mean that we do not care for colors! After doing some development and testing, we present you a new colorimetry-enabled release, code name "Red October"!

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
Haali Splitter 1.13.322.9 (CCCP Build)
LAV Filters 0.58.2.0-42306ee
MPC-HC 1.7.0.7859 (shows up as 7877)
xy-VSFilter 3.0.0."236"
211 with various backports and fixes.
General changelog:
Installer and settings applications
Added a Samsung H.264 decoder with an irrationally high merit that seems to come with a piece of software called Intelli-studio to the black list.
MPC-HC
The transition from the Navigate menu to the Play menu regarding audio/video/subtitle track selection is now more or less complete. The bug with MPC-HC overriding the splitter's choice with audio tracks is now also fixed.
MPC-HC now defaults to "fast seek" that only seeks to random access points if those are available to the player. You may disable it in the Tweaks tab in the options.
Fixed alpha channel parsing with vobsub subpictures. Certain previously unshown subpictures should now be visible.
Subtitle renderer sanity checks removed as they ended up being too strict in some cases. The crashing sample reported will still work as there is some additional memory allocation checking included now.
Enabled the CCCP LAV Filters as "internal" for MPC-HC, and enabled certain formats within it for better playback of certain formats:
DTS/AC3, HTTP, RTSP, UDP, RTP, MMS, MPEG Audio (yes, this includes raw MP3) and RFS
Various miscellaneous fixes resulting from the update of MPC-HC to the 1.7 stable release, with some fixes cherry-picked after that.
LAV
Enabled colorimetry information (color matrix, range) output in LAV Video via dwControlFlags with a white list. Mainline LAV only enables this if MadVR is somewhere in the chain, while this will enable it as long as the next filter in chain is one of the following:
VSFilter (auto-loading or the non-autoloading one)
VMR7/9
EVR (includes everything that uses the same CLSID, including all of the MPC-HC custom EVR-based renderers)
madVR
Various miscellaneous fixes resulting from the update of LAV Filters to the current git HEAD (42306ee).
xy-VSFilter
xy-VSFilter is now generally colorimetry-enabled as well. It will use the colorimetry information, such as the color matrix or range, that it gets from an upstream filter (say, LAV Video) and pass it forward if the next filter in chain is one of the following:
VMR7/9
EVR (includes everything that uses the same CLSID, including all of the MPC-HC custom EVR-based renderers)
madVR
Fixed alpha channel parsing with vobsub subpictures. Certain previously unshown subpictures should now be visible.
Re-introduced a patch for the Kasumi I420/YUY2 to RGB colorspace conversion routines as Lord was somehow able to reproduce the problem it fixes. Should not happen in general usage.
Subtitle renderer sanity checks removed as they ended up being too strict in some cases. Instead tried to make xy-VSFilter handle failed memory allocations in a more correct manner. The VSFilter subtitle rendering engine is old and rather memory-inefficient, so the only real fix for this would be to either rewrite it completely, or create a proper Windows port of libass (primarily without fontconfig).
Haali Package
Now built with the same toolchain as the rest of the CCCP package, namely VS2010 SP1.
Debug symbols are now available! Yes, this means we can now debug Haali's things.
Haali's renderer should now try and enforce top-down RGB. This should fix some slowness problems when feeding RGB to the renderer.

New CCCP Win8/Win7/Vista/XP Release! (2013-08-01)

The summer has shown us its better half, and it's time to for another release, code name "August Augmentation"! This August Augmentation release generally enhances efficiency of the playback paradigm, and updates the components, fixing reported issues.

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
LAV Filters 0.58.2.0-96814e9
MPC-HC 1.7.0.7670 (shows up as 7680)
xy-VSFilter 3.0.0."232"
211 with various backports and fixes.
General changelog:
Installer and settings applications
OGM/OGG has been switched over to Haali because of seeking difficulties with certain OGM samples in ffmpeg (see issue 2739 for future information). This was fixed in libav, but unfortunately the differences in the two projects' demuxers make applying the fix to ffmpeg's OGG demuxer useless.
MPC-HC
D3D Fullscreen can now be switched to windowed mode just like the normal full screen mode. The hotkey toggling D3D Fullscreen is now disabled by default so that newcomers do not accidentally switch to it and wonder what happened.
The audio switcher will now show all audio tracks available, including all the embedded tracks exhibited by the source filter, as well as the external tracks.
Various XySubFilter-related enhancements. This build will prefer XySubFilter to xy-VSFilter if the first is registered onto the system.
The resolution check in the subtitle renderer has been matched up to the one in xy-VSFilter, see the xy-VSFilter changes for more details.
Various miscellaneous fixes.
LAV
A validity check for Vorbis streams was corrected to not fail with certain correct Vorbis streams. See ffmpeg issue 2720 for more information.
"Default track" flags are now also enabled for video tracks.
The current chapter point in LAV Splitter's tray icon should now show the correct current chapter, instead of being around 10 seconds in the future depending on the amount of internal caching done.
Slight improvement in the transition between ordered chapters with LAV Splitter in case the chapter points weren't exactly at the right spot time wise.
PMP, NUT, HLS, FLIC and Avisynth (yes!) demuxing enabled in LAV Splitter by default.
Fully DirectShow Avisynth script playback does still need that the AVI/WAV File Source filter doesn't jump in front of it (that the Avisynth installer usually registers as the source filter for ".avs"). Either block this filter in MPC-HC or remove the source filter registration for this.
The new Avisynth demuxer is currently not exactly perfect in ffmpeg, Avisynth 2.6 is recommended for stability. See ffmpeg issue 2526 for more information.
Camtasia (TechSmith Screen Capture Codec), DV, QuickTime 8BPS, LOCO, FLIC and Go2Meeting video formats enabled in LAV Video by default. Most of these are minor, except for DV that has actually been found on someone's hard drive once.
Slice-based multithreading has now been enabled for YADIF in LAV Video.
xy-VSFilter
The resolution check for xy-VSFilter is now modified to block areas larger than 8000x500 samples, instead of checking if either width or height was larger than 4000. This is in a way more strict of a check, but on the other hand enables very long scrolling text to be shown again. The reason such a check is needed to begin with is because certain broken scripts make xy-VSFilter go Out Of Address Space on 32bit systems.
The colormatrix guessing has been fixed. Used to be always BT.601, now defaults to BT.709 or BT.601 depending on the resolution.
A fix from MPC-HC has been backported in order to fix WrapStyle = 3.
Seven commits applied regarding making xy-VSFilter's reconnection logic somewhat better. This fixes cases where xy-VSFilter would "OK" a change even though it had no way of pushing out the changed sample type to the following filter in the chain.
A fix from MPC-BE has been backported in order to fix rendering of vobsubs in Matroska using the "custom colors" feature (MPC-BE revision 1995).
UTF-8 parsing enhancements. Added support for U+10000-U+10FFFF UTF-8 encoded characters, and other backported fixes from MPC-HC.

New CCCP Win8/Win7/Vista/XP Release! (2013-05-30)

And now a new start-of-summer May release with LAV Filters 0.57, codename "Can't Change Codename Perpetually"! This should also contain something that should make life simpler for some XP users who used to have issues with our previous LAV-based releases.

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
LAV Filters 0.57.0.0-d8dc0ef
MPC-HC 1.6.8.7347 (shows up as 7357)
xy-VSFilter 3.0.0."220"
211 with various backports and fixes.
General changelog:
Installer and settings applications
Haali's 'Autoload VSFilter' checkbox in the settings application has been replaced with a LAV Splitter tray icon checkbox as part of the gradual Haali removal process. This setting can still be changed in Haali Splitter's settings.
A button for LAV Splitter's settings has been added to the settings application, and the buttons in general have been somewhat regrouped.
MPC-HC
Memory leaks have been fixed in MPC-HC that happened with files that contained chapters. Thanks go to Underground78 for quickly solving this issue, and to Phantasm for helping in debugging the problem.
The update checking mechanism question that pops up during first start-up of MPC-HC no longer comes up so that the playback would start behind or in front of it. The playback will not start before you answer the question.
Audio switcher's normalization and boost features have been updated. If you do not reset settings and use these features, you might get unexpected results. Do make sure to either reset settings, or go into the options and modify the settings to match according to your tastes.
LAV
LAV Video now prefers YV12 to NV12 on XP if a 4:2:0 YCbCr color space is being tried for output. This should work around or fix some of the problems that certain XP users have been having after the switch to being LAV-based.
A pop-up menu has been added to LAV Splitter for switching streams or editions, and jumping to chapters. Enabled by default in CCCP.
Many small changes to LAV Splitter that improve the scanning speed of Matroska files when using segment linking.
Default streams are now preferred to the special 'forced' streams that LAV Splitter creates internally in case of PGS subtitles. This makes subtitles show up more often, matching the behavior to when there are no PGS subtitle tracks available. Real 'forced' tracks still get selected by default in case such exist.
A problem with segment linking and Vorbis audio extradata changes has been fixed in LAV Splitter.
The FLAC channel mask from metadata is now used by LAV Audio, fixes playback of FLAC files with non-standard channel layouts.
JPEG2000 support has been added.
xy-VSFilter
A blacklist update from MPC-HC has been backported. Should improve xy-VSFilter falling out of the playback chain in case of a known application that doesn't like its existence, and most probably will not get fixed.
A couple of new NV12-to-I420/YUY2/RGB color conversion code paths have been added to vd.cpp's Kasumi-based solutions as a measure to work around some weird connections that xy-VSFilter happens to create for one reason or another.

New CCCP Win8/Win7/Vista/XP Release! (2013-04-20)

Finally! The first fully LAV-by-default release is here! Fixes the biggest problem of the post-FFDShow-tryouts releases, as well as corrects a bug in DVD subtitle rendering. Without further ado, a new CCCP for Win8/Win7/Vista/XP, codename "The Evil Within" (the second)!

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
Haali Splitter 1.13.138.14 (2013-04-14)
LAV Filters 0.56.2.0-b6f9b1f
MPC-HC 1.6.7.7082 (shows up as 7091)
xy-VSFilter 3.0.0."217"
211 with this patch, this patch, this patch, this patch, this patch and this patch.

A general bugfix release that fixes one full-blown crash bug, as well as tries to limit the harm and possible crashes caused by badly written ASS subtitle scripts. Better general playback performance can be most probably be attained now thanks to changes in MPC-HC as well as LAV Filters. Without shortening our ties, a new CCCP for Win8/Win7/Vista/XP, codename "The Evil Within"!

Updated components:
LAV Filters 0.55.3.0-4021e9d
MPC-HC 1.6.7.6978 (shows up as 6988)
xy-VSFilter 3.0.0."215" (211 with this patch, this patch, this patch and this patch)
General changelog:
Installer and settings applications
Added DiAVC to the "merit sanification" list in the installer. This makes sure that the CCCP's default decoder comes up as used in case this filter was installed before hand. Similar merit sanification was already done to DivX's H.264 decoder as well as CoreAVC.
Added MPC Video Decoder filter to the bad filters list of the installer. Many applications abuse old versions of this filter, and it does not really contain any features or capabilities that aren't already available in the preferred decoder in this pack.
MPC-HC
Switched back to a "normal" build of MPC-HC instead of a "lite" one as that actually ends up being both smaller as well as more useful in the end. Splitters built into the binary are still limited, but this should help people having certain kinds of trouble.
Currently built in splitter filters are as follows: AVI, DSM, DTSAC3, FLAC, MPEGAUDIO (raw MP3/AAC), SHOUTCAST, UDP and RFS.
VSync in the custom MPC-HC video renderers now defaults to off. This should enable better performance with and generally enhance the viewing experience with filters and files that would not give well usable frame duration values to upstream.
Dragging and dropping files onto the MPC-HC playlist should now bring up the playlist and work somewhat more intuitively.
The MPC-HC internal subtitle filter (ISR) will from now on block rendering surfaces bigger than 4000 pixels in width or height. This will stop most badly written ASS subtitle scripts from causing the subtitle renderer to crash because of lack of memory address space.
LAV
Updated LAV Filters to a development version that has a The Evil Plan-enabled ffmpeg. In other words, keeping buffers and having them work nicely in a multithreaded environment just became nicely simpler. This is a relatively big change, but it has gotten quite some testing by various people by now, so we decided to include it in this release. Speed-wise improvement in f.ex. yadif deinterlacing can be seen (~10%), and normal decoding probably is a percent or two faster, depending on the format.
Certain kinds of mpeg-ts files no longer cause LAV Splitter to try and load the whole file into memory in order to probe a stream.
xy-VSFilter
Backported MPC-HC commit 2a75078 that fixed invalid memory references during re-reading of a subtitle file when switching file reading modes.
Implemented a check similar to MPC-HC's commits 2c597d9 and a0d3a13 to block rendering surfaces bigger than 4000 pixels in width or height. This will stop most badly written ASS subtitle scripts from causing the subtitle renderer to crash because of lack of memory address space.

After two months of general development and testing, the CCCP team is ready to bring out a new stable release! This update addresses several issues that were brought to our attention after the last release, as well as contains general fixes and updates. Without further ado, we present a new CCCP for Win8/Win7/Vista/XP, codename "tseuQ ranoX" (has nothing to do with a certain sound card series from Asus)!

As newer CCCP playback packages contain quite a few rather large differences compared to the pre-2012 ones, if you at any point need to grab the last FFDShow-tryouts based release, it, with some minor script-related fixes, is available from here.
Updated components:
LAV Filters 0.55.3.0-1af3d7c
MPC-HC 1.6.6.6844 (lite, shows up as 6852 in many places because of a design decision by X from the MPC-HC team)
xy-VSFilter 3.0.0."213" (211 with this patch and this patch)
General changelog:
Installer and settings applications
The installer will now see if you have any Asus Xonar audio devices installed, and if such are found, will check if a feature called "GX mode" is enabled in the drivers. If the feature is found to be enabled, the installer will ask if you would like to disable it. Since this mode is known to affect various things negatively, we at the CCCP project recommend for it to be disabled at all times.
The settings application no longer should let you do things that need administrative rights if you have no way of elevating (UAC is really, really disabled).
Added the Moonlight H.264 decoder (''{04B31EE9-EC66-4CED-8FF4-A9E7E22D1D8B}'') as well as the Emuzed H264 Video Decoder (''{B667A41E-E41C-402D-A7B3-C7C1D962D26F}'') to the 'bad filters' blacklist in the installer. Both of them are old and completely broken for general DirectShow playback scenarios.
MPC-HC
The player no longer should have black borders around the rendered video surface as long as the player's window proportions match the video's.
There is now an option to set the auto-fit factor for auto-zoom's auto-fit feature.
Certain PGS blu-ray subtitles are now rendered correctly thanks to Underground78's fixes in color palette parsing.
The VSync functionality in the custom VMR/EVR renderers has been made work better with the DMO WMV decoder that comes with Windows Vista+.
LAV
Keyframe seeking in MOV/"MP4" -style containers has been added.
Handling of some aspect ratios in matroska has been made better.
General improvements in hardware decoding.
DVD subtitle animation support was improved.
DTS bit streaming has been updated to fall back from DTS-HD MA to standard DTS in case it is not supported by the receiver.
The LAV Splitter's loadup override patch has been updated a bit. Should now work better with blu-ray playlists and folders in case the user happens to have disabled the format in LAV Splitter's settings while still having the format registered for LAV source filter-wise.
xy-VSFilter
Patched to auto-load microDVD .sub files again.
Ported the PGS subtitle rendering fix from MPC-HC to xy-VSFilter as well. Both should now be more correct in rendering them.

On this day before the new year's eve, we have released again! And no, we are not dead. This release is one containing probably one of the biggest if not the biggest change sets in the history of this playback pack. A new rewrite-filled CCCP for Win8/Win7/Vista/XP, codename "Life After Mad Movax" (LAMM)! Download: Win8/Win7/Vista/XP.

General changelog:
FFDShow and its continuation, FFDShow-tryouts are now away, and instead we have pretty much everything except for Matroska splitting based on nevcairiel's LAV Filters.
The old NSIS-based settings application is now also gone, and currently there is an Inno-based solution which bases on two separate settings applications; one handles user space, and the other handles system-wide settings (administrative rights needed). We would love to hear opinions and possible bug reports on it.
This will most probably be used at the very least until XP's support will end. But at least no-one thinks that "there should be no releases before it is rewritten in something saner."
WebM is now properly handled by LAV because Haali fails at it for whatever reason unless you use his renderer.
LAV Video handles video decoding, and LAV Audio handles audio decoding. If you need hardware accelerated decoding, use LAV's. MPC-HC's "lite" version does not contain the internal DXVA filter (which is in all ways inferior to LAV's). There are still some quirks because of remnants of Haali still needed, and because of the newness of LAV, but in general it should work.
One thing that no longer works by default is TrueHD when used with Haali (in other words, Matroska). This is very unfortunate, but thankfully there is a relatively simple way to have those files play by switching to LAV for splitting.
In this case you should open the settings application, open the system settings application from it, and check the MKV checkbox from it on the LAV side. This will switch to LAV for all Matroska files (segment linking and editions do not work, but otherwise it should work fine).
We now use xy-VSFilter instead of MPC-HC VSFilter. For now xy-VSFilter gives the greatest performance for end users, and in general it renders things well. This is in line with the recent change of Aegisub's towards xy-VSFilter as well.
MPC-HC has been updated, and many fixes, including MadVR related ones, are included.
CCCP now uses MPC-HC's update check mechanism to check for new CCCP updates.
The build will write memory dumps when it crashes. These are useful for debugging, and help in finding reasons to problems related to MPC-HC.

And new components are here! Thanks to Nevcairiel we now have much better ISO Media Container (also known as mp4, based on mov), FLV, MPEG-TS parsing and splitting. Thus, a brand new LAV'd CCCP for Win7/Vista/XP, codename "Redundantly Redundant Redundancy"!

General changelog:
LAV Filters included. LAV Splitter is used for certain formats where Haali was lacking and where Gabest's FLV Splitter was used. LAV Video and Audio are off by default for the time being, but can be enabled if the user so wishes. Since H.264 decoding with LAV can be very much useful, it has its own checkbox in the CCCP settings application.
FLV Splitter, CoreWavpack removed. FLV will be split by LAV Splitter, and wavpack will be decoded by -tryouts, as libavcodec's wavpack decoder now supports all of the funnier parts of wavpack thanks to Daemon404 herping a derp at the libavcodec developers. Raw wavpack splitting not possible with default CCCP any more, and we recommend users to either use a proper audio player for that sort of thing, or mux the stream into a container.
After poking the libavcodec developers with the two types of samples that failed with the ffaac AAC decoder, those are now fixed. This includes things like gg's Moshidora and overall AAC channel count changes in transport streams. The first kind of files are actually broken, but they worked with faad2, so the decoder was adapted to not scream and stop with them.
DXVA settings removed from the settings app. It touched -tryouts DXVA which never really worked as well as MPC-HC's. If you absolutely, positively want to use DXVA -- we recommend enabling it in MPC-HC. Not that it is any more recommended than earlier.
Overall installer/settings application updates.
Start menu entry reordered, now FFDShow and LAV have their own folders, and "Filters" was renamed to "Other Filters".
MPC-HC's mpciconlib.dll removed. The default icons as well as our original icons both had their problems, and the mpciconlib library isn't exactly small. Now there will be one MPC-HC icon used for all media files, and most sizes should be there. We are open for suggestions on icons and related things.

Way overdue, a new bugfix CCCP for Win7/Vista/XP while we boil some new stuff up in our testing labs!

CCCP generally built with VS2010 SP1, thus official support for older-than-SP3 Windows XP and Windows 2000 is dropped.
Updated components:
FFDShow-tryouts 1.1.3887
MPC-HC 1.5.2.3268
Haali 1.11.96.14 (2011-03-03)
VSFilter 2.40.3252.2
General changelog:
Settings application now has the 'MT' checkbox removed, as libavcodec has multithreading in itself, and it will get used by default in case of multicore CPUs.
Non-admin users should now be able to reset their settings via the settings app.
Seeking keys in MPC-HC have changed, what used to be ctrl+left/right is now just left and right.
Newer libavcodec fixes a very rarely occuring bug in H.264 decoding in FFDShow-tryouts.
Minor uninstaller clean-up fix regarding FFDShow-tryouts' DXVA settings.
Installer fixes related to remembering old selections and having a static AppId.
...and probably some other things Hoser the Third has forgotten.

It's been a long time since the last release. Are you noticing a trend here?! We proudly present CCCP9+9, "NEIN NEIN NEIN". Yes, it was released at 9:09:09 GMT today!

* Things built with VS2008 SP1 and/or GCC 4.3.3. Using March 09 DXSDK.
